Fabric-laying machine



Oct. 14, 1930. c. .1. SUSSMAN FABRIC LAYING MACHINE Filed Feb. 28, 1929 Patented Qct. 14, 1930 UNETED STATES PATENT OFFICE CHARLES J. SUSSMAN, OF CQRbNA, NEW YORK FABRIC-LAYING MACHINE Application filed February 28, 1929. Serial No. 343,251.

a carrier upon which a bolt of cloth may be laid, and which is adapted to travel back and forth along the length of the table, laying out the cloth in layers while traveling.

Referring to said drawing, 1 and 2 indicate the frame of the machine. 2, 3 brackets ex tending upwardly therefrom and connected by bars 4, 5. A suitable support (not shown) may be secured on top of the sides 1 and 2 upon which a bolt of cloth may be laid, the free end of the cloth passing upwardly between the metallic bars 6, 7 which, when in contact, form part of an electrical circuit from the battery 8. The end of the bolt of cloth is first secured upon the right end of the table looking at the drawing, so that as the car travels leftwardly, the cloth is laid the length of the table, being gripped upon the table at the extreme leftward travel of the bar 6 by gravity, the same being secured in the ends of the brackets 9, 10, which are pivotally mounted upon the cross bar 4. In the motor circuit is the operating mechanism of the handbrake 11, surrounding the wheel 12, upon the motor shaft 13. This band brake is normally opened clear of the pulley 12 by the motor current, which energizes a magnet within the box 15, which draws the jaws of the handbrake 11 apart and keeps them apart until the motor circuit is opened when the spring 14 operates instantly stopping the through travel of the car or carriage.

16 indicates the motor having a shaft 13 carrying a sprocket wheel 17, and sprocket "chain 18, which engages the sprocket wheel 19 upon. the shaft 20, at opposite ends of which are sprocket wheels 21, carrying sprocket chains 22, which engage sprocket wheels 23, upon shafts 24, which also carry gears 25, which mesh with gears 26 upon spindles 27, carrying the wheels 28 of the car. Thus the car is traveling when the motor 16 operates, and in order to reverse the travel of the car, the current to the motor is reversed at each end of the travel of the same.

For this purpose, a frame 28 is slidably mounted in the brackets 29, 30, and at each end of the frame is provided contact clips 31, 32 adapted to engage switch clips 33, 34. Any well known form of circuit being used for con necting these switches and clips so that, when the clips 31 are in the switch 33, the motor travels in one direction while, when the clips 32 engage the switch 34, the motor and car travel in the reverse direction, and in order to provide for this change of contacts, a suitable stop such as 35, is mounted at each end of the table in the path of the end 36, 36 of the frame, so that, when the car travels leftwardly, at the end of the travel, the end 36 of the frame 28, strikes the left stop 35, bringing the contacts or terminals 31, 33 together, thereby reversing the direction of the motor until the end 36 of the frame, strikes the stop at the right end of the table, thereby connecting terminals 32, 34, again reversing the motor, to send the car or carriage leftwardly, and so on, until the entire bolt of goods has been laid, the tracks 37, 38 serving to guide the wheels or rollers 28.

39 indicates a magnetic device for projecting the plunger 40 left-wardly, the offset 41 of said plunger striking a cut-off switch 42 for disconnecting the motor 16, and said device 39 is in circuit with the battery 8 and bars 6, 7 so that when the cloth is completely laid, the carriage comes to an instant stop with. the motor disconnected and he brake 11 applied.

Of course it will be understood that various signature.

able switch member adapted to alternately engage said first mentioned member's at the end of each travel of said carrier. i

In testimony whereof I hereunto afix my CHARLES J. sussMAN.
